There were 29 Eddisons, 11 boys called Bran and six Sandors - the same number of boys that were given the name Nathanial last year. There were also five babies named Ramsay in 2015.

However, some names are yet to appear in the figures. According to ONS figures, if there are any children named after the evil King Joffrey, or after Eddard or Samwell since 2011, they may be the only ones.

The show does feature some more conventional names, so babies given these names may not have Game of Thrones fans for parents. There were 64 Neds, and 23 Jons, as well as 14 boys named Jaime.
